I have an OBX header with an RMW flex joint welded on to replace that dreaded donut gasket. I have wrapped it completely with header wrap and sprayed the heat coating on it. It is currently on the car and has only been started twice for about a minute or 2 since the wrap (but the header has some miles on it). The reason i am selling is because i ordered a Mynes Performance header. It should be ready to ship out this coming week when the other header arrives Im looking for $110 plus shipping Shoot me a pm if you are interested
